I have a catalog then I use a Taxonomy to hold it. In this I have two fields: "Key" and "Value".
Then I have a "Product" (a content type). "Product" has a "Key" field (using a term reference selector).
Once I set the "Key" for a "Product" I want that my users look the associated "Value", not the "Key".
Is it a default option I can not set?
Should I install a Module to do it?
